The land resource inventory of Sambar-1 Microwatershed was conducted using
village cadastral maps and IRS satellite imagery on 1:7920 scale. The false colour
composites of IRS imagery were interpreted for physiography and the physiographic
delineations were used as base for mapping soils. The soils were studied in several
transects and a soil map was prepared with phases of soil series as mapping units.
Random checks were made all over the area outside the transects to confirm and validate
the soil map unit boundaries. The soil map shows the geographic distribution and extent,
characteristics, classification, behavior and use potentials of the soils in the
microwatershed.
The present study covers an area of 663 ha in Yadgir taluk & district, Karnataka.
The climate is semiarid and categorized as drought-prone with an average annual
rainfall of 866 mm, of which about 652 mm is received during south-west monsoon, 138
mm during north-east and the remaining 76 mm during the rest of the year. An area of
640 ha (96%) in the microwatershed is covered by soils and about 23 ha by others
(habitation and water bodies). The salient findings from the land resource inventory are
summarized briefly below.
 The soils belong to 12 soil series and 17 soil phases (management units) and
7 land use class.
 The length of crop growing period is about 120-150 days starting from 1st
week of June to 4th week of October.
 From the master soil map, several interpretative and thematic maps like
land capability, soil depth, surface soil texture, soil gravelliness, available
water capacity, soil slope and soil erosion were generated.
 Soil fertility status maps for macro and micronutrients were generated
based on the surface soil samples collected at every 250 m grid interval.
 Land suitability for growing 26 major agricultural and horticultural crops
was assessed and maps showing the degree of suitability along with
constraints were generated.
 Entire area in the microwatershed is suitable for agriculture.
 About 95 per cent area of the microwatershed has soils that are moderately
deep to very deep (75 - >150 cm) and 3 per cent soils are moderately
shallow (50-75 cm).
 About 30 per cent area in the microwatershed has loamy soils, 36 per cent
clayey soils and 31 per cent are sandy soils at the surface.
 About 96 per cent area of the microwatershed has non gravelly (
